Yubico YubiKey 5 Nano Two Factor Authentication Security Key - Black - USB-A

I use this product on a Windows laptop and I find it to be extremely convenient. Being someone on the move, using this to generate the token is time-saving too. I'd suggest anyone who's using two-factor authentication to go for this.

Working good

it arrived on-time and well packed. this items is used for special purposes like storing secure transactions or crypto wallet. so who buy it are aware of its value. To me, it is one the best HSM in the market

I think some of the 1 and 2 star reviewers need to take more time to understand exactly what it is they're buying. Firstly, it's a MULTI-FACTOR device, it's not supposed to replace passwords (yet), hence the term MULTI-FACTOR, there are MULTIPLE FACTORS to your login procedure, the first one being your username and password, the second being this key. Secondly, it doesn't type out your password on screen, it types a cryptographically-calculated string which changes each time and is specific to the hardware key itself. The interaction of touching the device is in place to work with your chosen software when it prompts for a U2F device, where you need to press the key to activate it. This is to stop automated log ins when the key is connected, it requires a human to physically activate it. Pressing the key at any other time will output a meaningless code onto your computer, which means nothing to unconfigured software, so this is not a security risk. Thirdly, not all services support hardware keys yet. New hardware and software takes a VERY long time to be supported by all platforms and always starts with the biggest (Google, Microsoft, Amazon, Facebook, etc). You should check that the services you want to use this for actually support hardware keys. Lastly, this is supposed to be small. If you're complaining about it's size when there are other options available like the standard Yubikey 5 or Yubikey 5C, then that's your problem not the product's. This is supposed to be a static key that can be removed if necessary, such as for a personal laptop, and should be used in conjunction with another 2FA method as a fallback e.g. mobile authenticator app. This is a great product that does the job it's designed for. It's working well with Yubico Windows login software and a number of online accounts.

在宅ワークでデスクトップPCの使用がメインになったのとGoogleからパスキーを推奨するアナウンスがあり導入。 他の製品と比較してやや高価なものの、小さいためUSBコネクタに挿しっぱなしにしておいても引っ掛けて破損するといった事が無いのが安心。 念のためUSB AtoCの変換アダプタと合わせて購入しました。

Práctica, fácil de usar, brinda la seguridad para la que está hecha, resistente

正直高いですが、ソフトウェア周り及び各種証明の代金と考えれば納得できます。
